JONATHAN BADGER, on NEW YORK, N. Y.

- WINDOW-VENTILATOR;

SPECIFICATION forming part of Letters Patent No, 287,791, dated November6, 1883,

l 1 Application filed February 13, 1883. (No model.)

To all whom zitmay concern.- I

Be it known that I, JONATHAN BADGER, a citizen of the United States ofAmerica, re siding at New York, in the countyof New 5 York and State ofNew York, have invented certain new and useful Improvements in Window-Ventilators, of which the following is av specification, referencebeing had therein to the accompanying drawings.

This invention consists in a ventilator of certain novel construction,which is designed to be applied to the upper part of a window, for thepurpose of deflecting or throwing upward the incoming currentof freshair produced when the upper sash is lowered, at the same time permittingthe escape of foul air, the latter, as is well known, having a tendencyto rise and seek an outlet.

The novel construction of my ventilator is hereinafter fully described,and is illustrated in the accompanying drawings, in which Figure 1represents avertical cross-section, showing it in position withinawindow. Fig.

2 is a front View, partly in section. Similar letters of referenceindicate corresponding parts.

The letter Adesignates aframe of awindow, containing the usual sashes,BO, and also containing a ventilator which embodies my invention. Thisventilator consists of a vertical I shield,D, a horizontal ledge, D,attached to one side of the shield, and end pieces, D, at-

tached to both the shield and ledge, each of these parts beingpreferably made of wood. The longitudinal edge of the ledge D, which isits free edge, is provided with a packingstrip, 6, of'india-rubber orother similar material. Iheend pieces, D have less heightthan the shieldD, thus terminating below the top edge of the shield, and in applyingthe device to a window the end pieces are secured opposite to the sidesof the frame, with their upper edges abutting against the top of thewindowopening, and in such a position that the packing-strip e is in thevertical line of the inner surface of the upper sash, B, while theshield D stands off or away from the frame in an in: ward direction, italso projecting above the Window-opening, as shown in Fig. 1,whereby anopening, 8, is created between the shield andthe'fraine. If the uppersash, B, is now lowered a sufficient distance to bring its top baropposite the ledge D, the packing-strip e impinges against such bar andproduces an air-tight joint at that place, while the current of freshair flowing in through the vacant space above the sash comes in contactwith theshield D, and is thereby deflected upward,

so that it enters the apartment in that direc tion through the openingor passage 8, as indicated by arrow in Fig. 1. It is obvious that theopening 8 will also permit the escape of foul air, if any exists in theapartment, While in either case an injurious or undesirable draft isavoided. It will be noticed that the lowersuch length being of coursevaried according to the differences in the sizes'of windows.

Having described my invention, what I claim, and desire to secure byLetters Patent, is

A window-ventilator composed of the shield or deflector D, the ledge D,having its free edge provided with a packing-strip, and the end pieces,D having a less heightthan the shield, the whole being adapted for usesubstantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JONATHAN BADGER.
